Fresh hacks every day
The stable version of OpenOCD (an open source On-Chip Debugging software package) doesn’t have support for the ICDI protocol used by the Stellaris Launchpad board. But it is pretty easy to build your own OpenOCD from source after patching it to use the protocol.
We’ve already seen an open source tool used to flash binary images to the TI … Read the rest
The STM32 F3 and F4 Discovery boards have been around for a while now. We’ve looked at both separately and they’re impressive dev boards for the price. Now can get a closer look at each from this in-depth comparison of the two Cortex-M4 development tools.
To start off, both of the boards have the same size and footprint (there … Read the rest
The Netduino, a dev board built around the .NET Micro framework with the goal of being compatible with Arduino shields just got a huge upgrade.
The new Netduino Plus 2 features an upgraded STM32 ARM Cortex-M4 uC running at 168 MHz, improving on the original Netduino’s ARM7 running at 47 MHz. In addition to some more processing power, the … Read the rest
eBay isn’t only about counterfeit designer handbags and boxes of all-marshmallow Lucky Charms, sometimes there’s actually something useful for sale. [Matt] found a bunch of Chinese-made ARM development boards with integrated LCD displays on the ‘bay, but without a reliable toolchain, these boards – as cool as they are – are nearly useless. Thankfully, he figured out how to do … Read the rest
Wow, that’s a really simple hardware setup to supply your device with a 3G Internet connection. Better yet, the software side is just as simple thanks to the Vodafone USB Modem library for mbed. It will work for any of the cell data plans offered by Vodafone. The only problem you may have is not living in one of … Read the rest
We’ve seen a few builds featuring NXP’s LPC1114 microcontroller before. This chip – the only breadboard friendly ARM microcontroller available – comes in a ‘still a little too large for prototyping’ 600 mil, 28 pin package. We won’t hazard a guess why NXP chose this rather large package, but the good news is it’s possible to shave this chip down … Read the rest
[Mahmut] calls this project SmartBox. It’s a BeagleBone controlled LED marquee which can pull down information off of the Internet.
The project started with the display itself. [Mahmut] used six 5×7 LED modules to populate a circuit board he produced himself. The low side of the modules is controlled by some MBI5026 constant current drivers, with PNP transistors on the … Read the rest
